| Common Name | 3-Methyl-2-butenal |
|---|
| Description | 3-Methyl-2-butenal, also known as senecialdehyde or 3,3-dimethylacrolein, belongs to the class of organic compounds known as enals. These are alpha,beta-unsaturated aldehydes of the general formula RC=C-CH=O in which the aldehydic C=O function is conjugated to a C=C triple bond at the alpha,beta position. 3-methyl-2-butenal has been detected, but not quantified, in several different foods, such as common oregano, beechnuts, oval-leaf huckleberries, tea leaf willows, and red rice. This could make 3-methyl-2-butenal a potential biomarker for the consumption of these foods. 3-Methyl-2-butenal is a derivative of acrolein that is an alpha, beta-unsaturated carbonyl metabolite. It can be formed endogenously during lipid peroxidation or after oxidative stress, and is considered to play an important role in human carcinogenesis. The endogenously formed acroleins are a constant source of DNA damage, can lead to mutation, and can also induce tumours in humans (PMID:8319634 ). 3-Methyl-2-butenal, which is an unsaturated aldehyde bearing substitution at the alkene terminus, is a poor inactivator of the enzymes protein tyrosine phosphatases (PTPs). The inactivation of PTPs can yield profound biological consequences arising from the disruption of cellular signalling pathways (PMID:17655273 ). |
